RECORDING SIGNALING SYSTEM.

SPECIFICATION forming part of Letters Patent No. 439,295, dated October 28, 1890.

' Application filed May 17,1890. Serial No. 352,212. on model.)

To all whom it may concern.-

Be it known that I, WILLIAM JAMEs FRASER, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Visconsin, have invented certain new and useful Improvements in Recording Signaling Systems; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, whichform a part of this specification.

My invention relates to that class of recording signaling systems in which an electric circuit communicates with a central station and a number of subordinate stations or boxes, the electric circuit being used to send reports from the boxes to the central station. In such systems such reports are usually recorded upon a rotating disk controlled by a clock, to the end that the apparatus shall show the time at which the reports were transmitted from the various boxes.

It is my object to produce such a system in simple and inexpensive form.

In the accompanying drawings, Figure 1 illustrates in a general way one form of embodying my improved system. Fig. 2 is a detail of means employed to operate the system. Figs. 3, 4., and 5 are details of the transmit ting mechanism.

A is a disk for receiving the marking from the stylus. This disk may be of anysnitable form, and is to be rotated by clockwork. As this part of the system is already well understood, I do not show the mechanism used to support and rotate said disk.

13 B are boxes located at the several places to be visited by the watchman upon his rounds.

C is the conductor leading from the most remote of such boxes past each of the entire series and thence to the central station, where the disk A is located.

Fig. 3 shows in detail the construction of the boxes. \Vhile the mechanism of these boxes resembles that of the break-wheel boxes used in the ordinary fire-alarm systems, it differs from such boxes to a certain extentin its construction, and radically in its operation in conjunction with the apparatus at the central station. For the present it is sulficient to say that the wheel B is to be rotated by means of a key or otherwise. A brush B communicating with the conductor 0, bears continuously upon some surface of the wheel. Another brush B communicating with the ground through the conductor 0, reaches into the path of the teeth 13*, so that when the wheel is rotated in the direction of the arrow said teeth make contact successively with said brush, and whenever such contact is made the circuit is completed from the central station through the conductor 0, through the brush B the wheel B, the brush B and conductor 0 to the ground G.

D is the battery, preferably located at the central station 011 the conductor 0 leading from the stylus-operating mechanism to the ground G.

E is a wheel or disk provided with escapement-teeth and located at a suitable distance from the disk A.

E is an escapement-anchor engaging the wheel E and having its arm hinged at E The function of the wheel may be performed if rotated in either direction. At one side of the arm of the anchor are located a pair of magnets F. A portion of the conductor 0 extends to such magnets and constitutes the coils of the latter, and then connects with the arm of the anchor E. On the side of the arm of the anchor opposite the magnet F is located a contact-point F in such position as to form a stop for the arm of the anchor at that side and to make electric connection between itself and the conductor G through the arm of the anchor. A portion of the conductor 0 leads to said contact-point. Then when the anchor-arm is in contact with the point F the circuit is complete from the ground through the battery, the conductor 0 the magnets F, anchor-arm, and conductor G to the boxes B. Now when the brake at one of the boxes is closed the entire electric circuit is complete through the magnets F. hen this occurs, the poles of said magnets are energized, so that they draw the anchor-arm to them and away from the point F, thus breaking thecircuit. Then the circuit is broken, the magnets lose their energy, and the anchorarm is returned by the spring F again into contact with the point F, so that the magnets F are again energized and again draw the anchor to them, only to allow it to again return by the action of the spring F This action is not in itself new. The anchor forms what is known to electricians as a vibrating armature. It will be seen from the foregoing that as long as the circuit remains closed at one of the boxes the anchor E will vibrate and maintain the rotation of the wheel E, and that when such a wheel as is shown in in Fig. 3 is rotated by the watchman the anchor E will vibrate intermittently. First the circuit will be closed twice for a short period, then,for a long period, then three times for a short period, and then again for a long period. The aggregate length of the contacts made by such teeth may be made suflicient to operate the anchor E long enough to give the wheel E just one rotation, the wheel 13 being turned once by the watchman.

H, Figs. 1 and 2, is an arm extending from the wheel E to the disk A. At its upper end it bears a stylus H which may be apuncturing or denting point or a pencil or a pen or other like device adapted to mark the disk A. Said arm extends through suitable guides, as H At its lower end it is joined to the wheel E by a post E set at a suitable distance from the center of the wheel E, so as to cause the latter to operate as acrank in reciprocating the arm H. The latter should have a joint at I-I in order that the upper portion of the arm may move in parallel with the guides H When at rest, before a report is to be transmitted, the wheel E should so stand as to bring the arm H to its lower limit.

It will nowbe understood that when the circuit is closed at one of the boxes the anchor E will vibrate and turn the wheel E so as to raise the arm H, and that if the circuit is kept closed long enough the arm H will continue to ascend until the wheel has made a half-rotation, and then descend to its lower limit. If the circuit is made only long enough to partially raise the arm H, the latter will remain in such position to be further raised when the circuit is again closed, and so on until the wheel E has made a complete rotation and returned the arm to the original position. The object in View in changing the position of the arm is to enable the stylus to produce marks at varying intervals, whereby the reports sent in from the various boxes may be distinguished. For instance, if a report is to be sent in from box 24, it is intended to have the stylus produce two marks with a short interval between them, then a long'interval, and then four marks with short intervals between them. This I accomplish by causing the stylus to make an impression while at its lowest limit, then another at a point a little higher,

- then another after passing an interval which is long compared with the interval between the first two marks, then one after passing each of three short intervals. The mechanism to be employed for causing the stylus to make the impressions is a distinct branch or element of the apparatus or system. Different means may be employed for this purpose; but I deem it sufficientto describe the form illustrated by the drawings.

I I are a pair of magnets located behind the arm H. A portion of the conductor 0 leads to and constitutes the coils of such mag nets. and a portion of the conductor 0 leads from said magnets in the direction of the boxes. Under this arrangement the magnets I are connected in parallel with the magnets F, and there are no breaks in the portion of the conductor upon which the magnets I are located. Consequently the magnets Ibecome energized whenever the circuit is closed at one of the boxes, and so remain until such circuit is again broken at such box. Whenever the anchor E is vibrating, the magnets I are energized without interruption.

J is an armature located adjacent to the cores of the magnets I and held away from the latter by the spring J. The armature J is supported in any suitable manner-as, for example, by an arm J extending at right angles from said armature. When the circuit is closed at one of the boxes, the armature J is drawn against the cores of the magnet I, and the spring J returns the armature to its normal position, as in the drawings, as soon as the magnetsI de-energize upon the breaking of the circuit. armature J is utilized mechanically to actuate the stylus H'. A hammer L, having a handle L, is pivoted at L so as to bring the lower end of the handle immediately above the armature J and the head of the hammer opposite the upper portion of the arm II.

J 3 is any suitable projection supported by the armature J and extending into the path of the lower end of the handle of the hammer. Said projection is normally on the side of the handle L opposite the magnets I. The Weight of the hammer makes it tend to fall in the direction away from the arm H, while a spring L retains it in its normal position. On the side toward the magnetsI the projection J is inclined, and the adjacent face of the hammer is also inclined, and said projection may be made somewhat yielding. When the magnets I are energized, the armature J and the projection J are drawn toward the cores of said magnets, the projection J 3 slipping by the lower end of the arm of the, ham- This movement of the.

mer without moving the latter, or moving it but little. The parts in this position remain until the current through the magnets I is broken. Then the spring J draws the armature J and projection J 3 back to the normal position. In doing so the projection J enof the hammer-handle, the spring L which has been stretched by the movement of the hammer-handle, recoils and quickly draws the hammer in the opposite direction, so that the momentum acquired by the head of the hammer carries the latter into contact with the arm H with suificient force to drive the stylus against the disk A to mark the latter. It is to be remembered that the hammer L operates upon the breaking of the circuit at the boX operated by the watchman. If six marks are to be made upon the disk A to designate the box visited by the watchman, the breakwheel of said box must have at least six contact-points, and in order to effect an irregular spacing of the marks made by the stylus in response to the strokes of the hammer the armature J must be held against the core of the magnets I during intervals varying in length of time.

Referring now to Fig. 3, it will be understood from the foregoing explanation that as soon as tooth 1 makes contact with the brush B the stylus H will begin to move forward; but the circuit is soon broken, and upon breaking the hammer strikes the stylus. The entire mechanism at the central station is then at rest until tooth 2 makes contact with the brush 13 Then the stylus starts again to travel upward; but the circuit is soon broken, and upon breaking the hammer again strikes the stylus, thus making another mark a little above the first. Then the mechanism is again at rest until the brush B makes contact with tooth 3. The interval between tooth 2 and tooth 3 has no influence upon the distance between the marks made from said teeth to the disk A. The marking mechanism remains at rest whether such interval be long or short. Tooth 3 has an elongated contactsurface, and the stylus travels upward during the contact with such tooth in proportion to the length thereof, and the stylus does not make another mark until the contact between the brush B and said tooth breaks. Each of the teeth 4., 5, and 6 has a shortcontact-surface, and each such surface will cause the making of a short interval between two marks.

From the foregoing it will be seen that in the operation of my system the interval between the marks made upon the disk A depends upon the length of the periods during which the circuit is closed, and not, as is usually the case with this kind of apparatus, upon the spaces between the contact-points of the break-wheel.

The stylus will ascend during only the first half of the rotation of the wheel E, and during the remainder of the rotation it descends. The marking upon the disk A should be done by either the ascending or descending movement of the stylus. I have described it as being performed during the ascending movement. The rotation of the wheel E may be continued by means of the vibrating anchor until the original position is again attained. To effect the complete marking during the ascent of the stylus, the aggregate contactsurface of the break-wheel teeth used for such marking must be less than the amount which will cause the vibrating anchor E to rotate the wheel E more than half-way around. By means of a prolonged contact made by the break-wheel the vibrating anchor may return the wheel E and the stylus H to their original position without having the latter make any further marks prior to the attaining of such original position. For this purpose a prolonged tooth 7 may extend from a point near the end of the brush B toward the tooth 6 a sufficient distance to make the aggregate contact surface of all the teeth upon the break-wheel sufficient to cause the vibrating anchor to impart to the wheel E a complete rotation. Then when contact has been broken with the last breakwheel tooth used for effecting the marking to designate the box the brush B will make contact with the tooth 7, be it long or short, and continue such contact until just before the complete turn of the break-wheel has been effected. At this time the complete rotation of the wheel E and the return of the stylus H have been effected. At this momentthe contact between the brush B and the tooth 7 is broken and the hammer L again strikes the stylus; but the mark so made will be outside of the range of the marking which is to be read and no notice need be taken of it. Such a mark will be made at the conclusion of each operation of the apparatus.

The transmitting mechanism or boxes may be varied from the form shown in Fig.3 without departing from the principle involved. For example, in lieu of the wheel B, a segment of the wheel B may be used, the teeth being grouped upon the segment as upon the wheel. Then in operating such transmitting mechanism the segment is moved through an arc of a circle equal to the periphery of the segment.

In Fig. 5 the teeth are mounted upon a bolt or shaft, which is to be moved longitudinally to bring the teeth into cont-act with the brush B Thus in one case the movable part of the transmitting mechanism is a wheel, in another a segment of a wheel, and in another a bolt or shaft.
